0-100% dimming or different
lighting effect; workable with single color, bi-color, RGB LED lamps.
ith the standard RDM remote device management protocol, supports DMX512 signal
bi-directional communication, achieves remote management of reading and writing DMX address
(DMX master controller must recognize the RDM protocol). Realize
RDM Mode: The dip switch 1-10 are OFF.
FUN=ON (the 10th dip switch=ON)
Self-testing Mode:
FUN=OFF (the 10th dip switch=OFF)
DMX Mode:
Setting DMX addresses with dip switch 1-9
FUN=OFF (the 10th dip switch ) Mode=OFF DMX
3.1 How to set DMX address via dip switch:
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37. E.g.3: Set Initial Address To 178.
001+004+032=37 002+016+032+128=178
DMX address value = the total value of (1-9), to get the place value when in “on” position,
otherwise will be 0.

4. Wiring Diagram:
*
An amplifier is needed when more than 32 decoders are connected, signal amplification
should not be more than 5 times continuously.
* If the recoil effect occurs because of longer signal line or bad line quality, please try to
connect 0.25W 90-120Ω terminal resistor at the end of each line.
